Description: This device is formed by three independent 8-Input NOR gates.

Pin Names:
Vdd - Positive Supply Voltage [BV to 15V]
Vss - Ground
A1, B1, C1, A2, B2, C2, A3, B3, C3 - Inputs
Q1, Q2, Q3 – Outputs

Operation Mode:
* The logic signals are applied to the -E-E-E- inputs and in the output. The result is given according the truth table.

Other Devices:
The 4001 is a Quad 2-Input NDR Gate.
Applications:
Logic Functions
Digital Amplifiers
Oscillators
Observations:
Any gate can be used as a 2-Input NOR gate if the remaining input is put to ground.
